Astronomers find a third type of supernova and explain a mystery from 1054 AD.

Yes, the magnetosphere is weakening. It does that from time to time.

The Universe isn’t just expanding, the expansion is also accelerating. If that’s true, how will the Milky Way and Andromeda eventually merge?

On New Year’s Eve 1899, the captain of this Pacific steamliner sailed into history. Or did he?

Due to a crust of carbon, the absence of oxygen, and constant bombardment from meteorites, the planet Mercury may be littered with diamonds.

Quantum entanglement may remain spooky, but it has a very practical side.

The discovery calls into question the few things scientists know about these powerful astronomical phenomena.

The conservation of energy is one of the most fundamental laws governing our reality. But in the expanding Universe, that’s just not true.

In terms of the planets we’ve discovered, super-Earths are by far the most common. What does that mean for the Universe?

Archaeologists turn to other scientific fields to fill in the picture of how victims lived and why they died.

In physics, we reduce things to their elementary, fundamental components, and build emergent things out of them. That’s not the full story.

Break into London Zoo? Illegal, but it would improve the London Circle Walk

If you’re a massless particle, you must always move at light speed. If you have mass, you must go slower. So why aren’t any neutrinos slow?

Passing chunks of ice can fertilize ocean waters and play a role in the planet’s carbon cycle.

The neutrino is the most ghostly, rarely-interacting particle in all the Standard Model. How well can we truly make “beams” out of them?

This year’s Nobel Peace Prize ceremony sends yet another strong message to Russian president Vladimir Putin.

To the Greek philosopher, all of our actions ultimately aim at our own pleasure.

Many were expecting extremism survivor and free speech advocate Salman Rushdie to take home the Nobel Prize in Literature, but Annie Ernaux beat him to it.

Venus Life Finder could launch as early as 2023.

After decades of development, whether NASA’s Webb succeeds or fails all comes down to five critical milestones that are only days away.

New research finds that dinosaurs were already adapted to living in cold climates before the end-Triassic mass extinction. But how?

Fossils of Australopithecus in a South African cave are one million years older than previously thought. This challenges the consensus that humans first evolved in East Africa.

If light can’t be bent by electric or magnetic fields (and it can’t), then how do the Zeeman and Stark effects split atomic energy levels?

Tiny fluctuations in old Kepler data reveals four runaway planets that are reminiscent of Earth.

We’ve already observed three cases where it’s happened. When you look at an object in space, it’s pretty easy to tell if it’s a star or a planet. Stars are […]

Einstein’s most famous equation is E = mc², which describes the rest mass energy inherent to particles. But motion matters for energy, too.

Back in 1970, Sister Mary Jucunda wrote NASA, decrying large investments in science. A former Nazi’s legendary response is still relevant.

With a finite 13.8 billion years having passed since the Big Bang, there’s an edge to what we can see: the cosmic horizon. What’s it like?

The new record-holder opens up a literal Universe full of possibilities. Someday, even our own Sun will eventually run out of hydrogen fuel in its core, bringing a tremendous set […]

From the present day all the way to less than 400 million years after the Big Bang, we’re seeing how the Universe grew up like never before.
